10 Claims.

This invention relates to improvements in typewriting machines and moreparticularly to card feeding means therefor.

An object of the invention is to provide means which may be used withany Varityper machine to feed cards without changing the construction ofthe machine.

In the Varityper machine the printing instrumentalities comprise a typecarrier or shuttle which may be rotated by the key levers to select thetype or carry it to the printing point where a hammer co-operates withthe selected type to print. A work sheet is fed vertically upwardlybetween the type shuttle and the hammer by suitable feed rollersarrangeda considerable distance beneath the printing point.

In carrying out the invention there is provided a frame or card holderwhich is very thin and may be introduced between the feed rollers to befed up and down by them with the card held thereon.

Heretofore it has been impossible to type on the lower edge of the cardbecause the feed rollers are located considerably below the printingpoint.

A feature of the invention relates to means including a holder wherebyit is possible to present the lower edge of the card or work sheet tothe printing point, for typing, while the card holder is still in thebite of the feed rolls.

Another feature of the invention is to provide, in the card holder, acut-out or aperture through which the printing hammer of the machine mayact on the card.

Other features and advantages will hereinafter appear.

In the drawings which form part of the specification Fig. l is a frontelevation of the carriage of the machine showing the invention appliedthereto;

Fig. 2 is a vertical section taken on the line 2-2 of Fig. l; and

Fig. 3 is a perspective view of the card holder.

Similar reference characters represent similar parts throughout theseveral views.

The machine includes a main frame 10, only a fragment of which is shown,having a track 11 secured thereto. A carriage 12 has a bar 13 by whichit may travel back and forth on the track 11 through the medium ofanti-friction balls or rollers 14. The upper end of the carriage has abar 15 engaged by a relatively fixed roller 16 and a bracket 17, toguide said carriage.

A relatively fixed feed roller 18 is rotatably supported on the carriageby a shaft 19. A releasable feed roller 20 co-operates therewith to feeda work sheet from a basket 21 on the carriage. The roller 20 issupported on a shaft 22 rotatably supported on two arms 23 secured to arock shaft 24 on the carriage. A spring 25 coiled around the shaft 24presses the roller 20 against the roller 18.

The feed roller 20 may be rotated by the usual line spacing mechanismincluding a line space wheel 26, or by means of the usual finger wheel27. Said feed roller may be released, for the insertion or the removalof the work sheet, by a release lever 28 which, when actuated rearwardlyabout the axis of the shaft 22, engages a fixed stud 29 on the carriageto force the feed roller 20 away from the roller 18 against the actionof the 7 spring 25. The stud 29 engages in a notch 30 of the lever 28 tohold the latter in its released position.

The work sheet is fed upwardly to the printing instrumentalitiescomprising a type shuttle 31 and a hammer 32 to co-operate therewith,the printing point being some distance above the bite of the feedrollers. The machine thus far described is of the usual Varityperconstruction.

The card holder 35 of the present invention comprises'two verticalmembers 36 joined by a horizontal bar 37 to form a permanently fiat H-shaped frame composed of sheet metal. Resilient fingers 38, suitablysecured to the vertical members or arms 36, press against the upward 5extending portions thereof to hold a card 39 there on. The fingers 38are also composed of sheet metal and are bent to provide shoulders 40with which the bottom edge of the card engages to align the card on saidholder. The extreme upper ends of the fingers 38 are bent away from themembers 35 to permit the card to be readily inserted between fingers 38and the members 35. It will be understood that the upper portions of thearms 36 form with the cross bar 37 a cut-out through which the hammer 32may act on the work sheet.

The card holder 35 may be introduced between the feed rollers 18 and 20,while the latter are in their released position, and may be pusheddownwardly until the lower ends of the vertical 1 members 35 engage thebottom of the basket 21 thus aligning the card holder on the carriage.The feed roller 20 may then be rendered effective by moving the releaselever 28 forward and the card holder 35 may be subsequently fed by theusual line spacing means. The usual aligning gauges 41 may also be usedto align the card holder.

It will be understood that the members 36 of the card holder extendconsiderably below the horizontal bar 36 thereof so that they may stillbe in the bite of the feed rollers while the bottom edge of the card isat the printing point as in Fig. 2. In other words with this arrangementit is possible to write to the bottom edge of the card even though thefeed rollers are a considerable distance below the printing point.

It will further be understood that part of the card, the upper endthereof may be typed, if desired, without the use of the holder but inorder to type near the bottom edge of the card or of an ordinary worksheet the holder is used to control it after the lower edge passesbeyond the bite of the feed rollers, said card holder thus serving as anextension for the lower end of the card, It will also be understood thatthe card may be mounted on the holder before or after the latter isinserted in the machine.

While the preferred embodiment of the invention has been shown it shouldbe understood that changes in the form, arrangements, proportions, sizesand details thereof may be made without departing from the scope of theinvention as defined in the appended claims.

I claim:--
